R/W characteristics means the function is with read and write characteristics. For example, "communication
control command" is writing characteristic and control the inverter with writing command (06H). R
characteristic can only read other than write and W characteristic can only write other than read.
Note: when operating on the inverter with the table above, it is necessary to enable some parameters. For
example, the operation of running and stopping, it is necessary to set P00.01 to communication running
command channel and set P00.02 to MODBUS communication channel. And when operate on "PID
reference", it is necessary to set P09.00 to "MODBUS communication setting".
The encoding rules for device codes (corresponds to identifying code 2103H of the inverter)
Code high
8bit
01
Note: the code is consisted of 16 bit which is high 8 bits and low 8 bits. High 8 bits mean the motor type
series and low 8 bits mean the derived motor types of the series. For example, 0011H means CV30
inverters.
7.4.3 Fieldbus ratio values
The communication data is expressed by hex in actual application and there is no radix point in hex. For
example, 50.12Hz can not be expressed by hex so 50.12 can be magnified by 100 times into 5012, so hex
1394H can be used to express 50.12.
A non-integer can be timed by a multiple to get an integer and the integer can be called fieldbus ratio values.
The fieldbus ratio values are referred to the radix point of the setting range or default value in the function parameter list. If
there are figures behind the radix point (n=1), then the fieldbus ratio value m is 10
